Yes it is. Of course she ought to be punished if it's transpired that she's bullied someone ( although many bully from a feeling of powerlessness and insecurity and that needs addressing before the bullying ends). What Mr Cox has succeeded in doing is isolating himself from his daughter who might be feeling overwhelmed, afraid, embarrassed and be 'getting in first', without knowing further details it's impossible to say, but in doing so he's shirked his responsibility as a father who ought to be the person a chi;ld can always turn to. He should have dealt with it quietly sensibly and so the girl can use it to learn that bullying is not the way forward. As is it he's a puffed up posturing lackwit who is a prime example of what a bully look like. I bet his family are miserable, and I bet that's why the child bullies because she's seen him do it, and here he is again proving her point. Dreadful parenting.
